This invention relates to water and like spraying devices and is concerned with a hose pipe fitting which will give a discharge in either a solid jet-form or as a fan-wise spray.

The invention consists in a liquid spraying device comprising a nozzle giving a solid jet discharge, a tting secured upon said nozzle having an arcuate or segmental gap or opening opposite to the end of the nozzle, the said gap or opening being clear of the jet discharged by the nozzle, a piston like part movable in the fitting in a direction at right angles to the nozzle axis and adapted to obstruct the jet issuing from the nozzle so that the liquid iills the fitting and issues from the arcuate or segmental gap or opening as limited by the edge of the piston skirt.

The invention further comprises the arrangement wherein the piston skirt is slotted to pass over the end of the nozzle which therefore prevents the piston from turning during its axial movements.

The invention further comprises a cap on the fitting which is turned to adjust the position of the piston within the skirt through the medium of a screw threading into the piston and passing through and held against axial movement in a plate secured in the tting.

Referring to the accompanying sheet or" explanatory drawings:

Figure 1 is an axial section through a nozzle and fitting to give a liquid discharge in solid jet form or as a ian shaped spray, constructed in accordance with this invention.

Figure 2 is an end View of Figure 1 looking from left to right.

Figure 3 is a sectional end view on the line 3 3 of Figure 1.

The hose pipe (not shown) is attached at a to the nozzle b which gives a solid jet c. Upon the nozzle end is threaded at d a fitting e which has an arcuate opening f extending around the side through' which the jet c is projected. Such opening has of itself no effect upon the jet c but is clear thereof.

Within the tting e is a piston like part g which is axially adjustable in the fitting by means of a screw h which threads through the piston and through a plate i secured in the end of the fitting. There is a cap i upon the end of the screw by which turning of the latter is effected. The screw is capable of rotary movement in but not axial movement through the plate i and the piston g is prevented from turning by `having a slot therein at lc into which the end of the nozzle b passes.

With the parts in the position shown in Figure l, there is a solid bore discharge from the end of the nozzle b. If, however, the cap 7 be turned to lower the piston like part g, the jet c will be obstructed by the bottom edge of the piston skirt and the jet will be throttled and caused to issue through the arcuate or segmental gap f, the depth of which is determined by the extent to which the piston g is lowered in the tting e. The issuing jet is now spread out fanwise from the iitting and has considerable covering power.

What I claim is:

A liquid spraying device comprising, in combination, a nozzle giving a solid jet discharge at its end, a fitting secured upon the end of said nozzle having an arcuate or segmental gap or opening at its side opposite to that which is secured upon the end of the no-zzle, the said gap or opening peing of size suoient to allow of the passage of the jet delivered by the nozzle, a piston movable in the'tting in a direction at right angles to the nozzle axis so as to close to a greater or less extent the gap or opening in the iitting, the end of the nozzle entering a slot in the piston skirt to prevent turning movement of the piston, a screw threading into the piston and passing at a non-screwed part through a part of the fitting, means preventing axial movement of the screw relatively to the fitting, and a cap secured upon the end of the screw and extending over the f1tting for turning the screw and causing axial movement of the piston, which when it partially closes the gap or opening is adapted to cause a jet from the nozzle to spread out fanwise as it issues from the tting.
